DETAILED DESCRIPTION OF THE DRAWINGS

The following detailed description refers to the accompanying drawings. The same or similar reference identifications may be used in the drawings or in the description to refer to the same or similar parts. Also, similarly named elements may perform similar functions and may be similarly designed, unless specified otherwise. Details are set forth to provide an understanding of the exemplary embodiments. Embodiments, e.g., alternative embodiments, may be practiced without some of these details. In other instances, well known techniques, procedures, and components have not been described in detail to avoid obscuring the described embodiments. Various embodiments disclose methods and system for Internet or power resiliency as described below. In some preferred embodiments of the invention, the system is called a constant connection (CC) system, in others, the system is called a smart connector; the terms are used interchangeably in this disclosure.

The following describes some of the features in various embodiments and the mechanisms for implementing those features. Some embodiments include a smart connector that provides robust connection of a computer system to the Internet. In the embodiments, the smart connector provides robust connection of the computer system to the power supply by providing an Uninterrupted Power Supply (UPS). In some embodiments, the smart connector provides both the robust connection to the Internet and the UPS.

At a high level, embodiments of the invention re-establish Internet connectivity for the majority of cases when Internet modems and routers go offline or degrade service, e.g., when the Internet Service Provider (ISP) is down, or when the power is out. Embodiments of the invention are useful for home use to minimize Internet outages. Other embodiments are useful in a “lights-out” computer room. Embodiments of the invention are designed to minimize Internet outages by monitoring common conditions such as power and ISP outages and less common conditions such as such as over temperature, under temperature, and water leaks. Embodiments of the invention are able to power down and restore power to related auxiliary devices, for example, by using AC plugs that are under program control. A power down and power up will often fix many issues with such auxiliary equipment. Another feature of embodiments of the constant connection (CC) system is to maintain power during power outages.

FIG. 1 illustrates a flow diagram of a preferred embodiment of a process that may be programmed into the smart connector. In step 101, the smart connector system is monitoring the Internet connection to detect Internet outages. The outages may be due to problems from the service provider, or with the modem, or router. If an outage is detected, in preferred embodiments, a state of the Internet connection is set as “failed”. The system pings external sites to test connectivity, step 103. If a response to the pinging is received, in preferred embodiments, the state of the Internet connection is changed to “degraded”. Presuming that the system is proven to be connected to the Internet by the ping test, in step 105, tests are performed to detect Internet performance degradation. For example, the system may stream music and video, or another large file, to check for smooth streaming. If the performance test indicates good performance, step 107, the process returns to monitor the Internet connection to detect Internet outages, step 101. In preferred embodiments, the state of the Internet connection is changed to “healthy” if the large file is received within a predetermined time.

If not, that is the test indicates poor performance, in step 109, the system reboots the modem and router to eliminate the degradation. If the reboot is successful, the system returns to monitoring, step 101. If the reboot is not successful, the system notifies user by sending a hub problem notification by instant messaging, step 113. In preferred embodiments, the system state is reported as a problem in the hub problem notification, if the Internet connection state is “failed” or “degraded”.

FIG. 2 illustrates a flow diagram of a preferred embodiment of a second process or test that may be programmed into the smart connector system. In step 201, the system monitors for an Internet failure or performance degradation. If a problem is detected, in step 203, the system reboots router and modem during an Internet failure or performance degradation. In step 205, the checks for connectivity and degradation are performed as described above in association with FIG. 1. If good performance has been determined, the system goes back to monitoring for Internet failure or performance degradation, step 201.

If the rebooting does not restore service, the system proceeds to isolating the problem to particular components, step 209. In step 211, the system diagnoses Internet failures caused by the Internet service provider. In step 213, the system diagnoses failures due to the cable/DSL/FIOS modem. If a potential modem problem is detected, the system reboots the modem, step 215. After rebooting, the system checks for connectivity and degradation. If the problem persists, the system sends a hub problem notification by instant message to the user noting they should contact their service provider, step 219. The service provider would isolate the problem to their service or the modem.

FIG. 3 illustrates a flow diagram of a preferred embodiment of a third process or test that may be programmed into the smart connector. In step 301, the system monitors for an Internet failure or performance degradation. In step 303, the system diagnoses one or more Wi-Fi router failures. Then, in step 305, the system reboots the router. Next, in step 307, the system checks for connectivity and degradation. If the problem persists, step 309, the system sends an instant message to the users, e.g., a hub problem notification advising them seek expert help to reconfigure or replace the router.

In preferred embodiments of the invention in which alternative routes are available to the Internet, the system reroutes Internet connectivity, e.g., through cellular network connections, step 311. The ability to reroute Internet connectivity when a hotspot is available is an advantage of embodiments of the invention when the ISP or Internet modem are down and when rebooting the modem did not fix the problem. Embodiments of the invention automatically reroute the Internet connection without the need to change network settings on each Wi-Fi or wired device. Some embodiments notify the user by instant messaging of this change. This mechanism allows for connectivity in areas with cellular connectivity, but no landline Internet connectivity, i.e. when a cellular hotspot is available.

FIG. 4 illustrates a flow diagram of a preferred embodiment of a fourth process that may be programmed into the smart connector. In step 401, the system monitors UPS battery health. In step 403, the system continuously measures the UPS voltage output. If the system detects a drop below certain thresholds, step 405, the system sends an instant message warning of the UPS issue to the user, e.g., a hub problem notification or a UPS problem notification.

The process can also optimize UPS battery life in preferred embodiments. As shown in in step 409, once a month, or some other predetermined interval, the system drains the battery to 20% of battery life left and then recharges it. Those skilled in the art would recognize that other levels of battery charge could be used in alternative implementations of the invention. During recharge, the system monitors the voltage level to determine the remaining battery life.

Other tests for common UPS failures are included in some embodiments of the process, shown generally as step 411. For example, the system cuts the connection to an external power supply to the UPS using a timed switch under program control. If the unit continues to work, the UPS is OK, step 413, and the process returns to step 401. In preferred embodiments, the timed switch reconnects after a preset time if the timed switch is disconnected. If not, the program-controlled switch resets which restores power and causes the smart connector unit to reboot. If successful, the process returns to step 401. If not, the system sends an instant message, e.g., a UPS failure notification, noting that the UPS needs service. In preferred embodiments, if the UPS is OK a healthy UPS notification is sent, e.g., by instant message. In response to a successful reboot of the smart connector, the UPS failure test time is set to a large number in one preferred embodiment of the invention.

In a preferred embodiment of the invention, testing for a UPS failure includes setting a UPS failure test time to the present time. After an automatic reboot of the smart connector, the time of the last reboot of the smart connector is read. If the time of the last reboot is after the UPS failure test time, a failed UPS notification is sent, e.g., by instant message.

The hub problem notifications in the instant messages discussed above are preferably specific to report the detected anomalies and the suggested service through instant messaging. For example, in response to detecting a modem problem, a modem problem notification detailing the problem is sent. In response to detecting a router problem, a router problem notification detailing the problem is sent. If the UPS has failed, the smart connector sends a failed UPS notification. Instant messaging is a preferred means to send the hub problem notification as the system cannot report via email when the Internet is down.

In preferred embodiments, the smart connector uses other additional means to report status. In one embodiment, the system displays green, yellow and red LEDs to show status. Green indicates normal operation. A yellow LED indicates that preventative action is needed. If Internet connection is available, the user can check system status though a web page interface. A red LED indicates that the system has a serious issue.

In preferred embodiments, the system would receive automatic firmware upgrades from the company that, for example, supplied firmware. A web interface is used to setup and monitor the constant connection device. A preferred implementation uses an embedded-Linux microsystem with downloadable firmware. A web page interface is used for configuration and status. In the described embodiment in FIG. 5, the system has no integrated console or display. The system comes up running when batteries have failed and continues without discontinuity when AC power is restored. A built-in UPS with UPS battery maintains power during power outages.

Other embodiments of the invention can use other orders of Internet diagnosis than those described above in connection with FIGS. 1-4. For example, in response to a detected problem, the system could immediately reboot both the modem and router. Then, the system powers up the modem. The system waits for Internet connectivity which can be checked by pinging through a wired Ethernet port. Next, the system powers up the router. The system checks for router connectivity by pinging external sources with path from the constant connection device to router to modem to ISP. The example above is merely exemplary, and the order of any of the self-tests discussed above is not order dependent.

During a landline or modem outage or service degradation detected by the system, if rebooting the cable modem and Wi-Fi router do not fix the problem and a hotspot is available, in preferred embodiments, the system switches to a cellular hotspot, if a hotspot is present. Next, the system changes its routing path from the cable/DSL/FIOS modem's Internet address to the hotspot's Internet address. The system connects to a hotspot though its intranet Wi-Fi port. Alternatively, to connect to dedicated or smartphone hotspots, the system routes that signal through a wired Ethernet connection to the Wi-Fi router. The router transmits to the Wi-Fi devices as normal. Other devices do not see a change in the network name or address. In preferred embodiments, the system UPS can maintain power to the hotspot device. In areas without landline Internet, but with cellular service, alternative embodiments of the invention maintain a hotspot connection using the same technique as above.

FIG. 5 shows a smart connector (constant connection unit) according to a preferred embodiment. In some embodiments, the constant connection unit 500 maintains Internet service and power through conditions that cause Internet outages. Referring to FIG. 5, certain components are located within the smart connector or constant connection unit 500 while other depicted components are part of the overall Internet hub which provides Internet connectivity. Microprocessor system 501 stores an embedded Linux operating system as well as the firmware which performs the monitoring and tests which the system performs.

The Wi-Fi unit 503 maintains a Wi-Fi connection with Wi-Fi enabled components. Two wired-Ethernet ports 505 maintain Ethernet connections via Ethernet. An internal voltmeter 507 monitors the battery/voltage of system components. A DC UPS 509 comprises a large battery 510 and a 120V AC to 12V DC power supply 511 which provides 12 V DC power to other components of the system in the event of power failure. A 12 V DC to 120 V AC inverter 513 converts battery power to AC voltage. A switch 514, under program control, cuts power to UPS upon command from the microprocessor 501. The switch 514 resets to closed (on) during a power failure to the unit. Optionally, the system includes AC plugs 537 under program control to reset devices such as hotspot 517 and cable, dish, FIOS modem device(s) 533 as well as router 535. The AC plugs can also control other AC power 539, e.g., a power strip, which powers other devices such as monitor 540 and printer 542. The AC cord 515 connects to an AC wall outlet and/or optional auxiliary UPS 545.

The optional dedicated hotspot or Smartphone hotspot 517 allows embodiments of the invention to reroute the Internet connection. Also optionally, the system can include a set of LEDs which indicate system status, e.g., Green LED 521, Yellow LED 523 and Red LED 525. Other optional sensors such as temperature sensor 527, fire/smoke sensor 529, and auxiliary sensor jack 531 can be used to monitor the system environment. The modular sensor connection for auxiliary sensors 531 can be used as an input for water, sound, and other sensors in a home automation system. A water sensor is used to detect leaks, a sound sensor detects environmental conditions such a failing system fans. Other sensors such as motion, light, amp meter and pressure sensors can be coupled to sensor jack 531. An optional rooftop cellular-signal repeater is used for areas with poor cell-signal strength.

In embodiments of the invention, the system sends instant messaging texts containing system status and suggested remedial actions to a user smart phone 541 via Wi-Fi unit 503 or smartphone hotspot 519. Internet Service Provider 543 is shown coupled to the cable, dish, FIOS modem device(s) 533. The reader will understand that in most implementations of the invention the cable, dish, FIOS modem device(s) are alternatives, rarely will all three be in the same Internet hub.

By having an integrated UPS, the smart connector can be programmed for UPS failure self-test, UPS battery health monitoring and UPS battery maintenance to extend its life as discussed above. Also, as is discussed above, the system is programmed for constant testing for Internet outages and constant testing of network performance degradation. The system provides transparent rerouting through available hotspots during Internet outages without other devices having to reselect their wireless network. Further, in preferred embodiments of the invention, the system is programmed to automatically reboot the modem and router in the event of detected problems which fixes most connectivity issues. In one preferred embodiment, the system brings them up in sequence, first the modem, then the router, with a pause after restoring power to the modem.

The present invention has many advantages over the prior art. By providing processes to test for Internet outages and degradation the constant connection system performs constant monitoring for Internet connectivity prevent interruptions before they occur. The constant connection system tests Wi-Fi system, wired router, modem and the ISP connections sequentially. If the pings respond normally and there is non-jittery audio streaming (good performance) then the monitoring is resumed. The constant connection system also removes the burden of troubleshooting from the user by taking action if the connections or performance are out of spec. In preferred embodiments, the general actions are that if CC system detects network connectivity or degradation issues, it reboots the modem, router or other peripherals. Connectivity is tested by pinging Internet servers; performance degradation can be detected by audio streaming or other large files. If the reboot fails to resolve the problem, the system attempts to isolate the problem and reroute the Internet connectivity around the problem. For example, the system tests to determine if Wi-Fi broadcasting has failed. If so, the system bypasses Wi-Fi broadcast by using a connection via wire to a router wired to a modem and then to the ISP. Alternatively, if the system test reveals that the router has failed, the system bypasses the router to test if it is working. The constant connection system is wired to a modem and then to the ISP. Further tests reveal if the modem failed or if the ISP service is down.

Further, the constant connection system programmatically self-tests the components which maintain the Internet connection. For example, the system monitors UPS-battery voltage. To test UPS operation, the system cuts power to UPS to test if it is operational through an AC power outage. The constant connection system includes a smart UPS with self-test, constant monitoring and periodic battery conditioning. The constant connection system also provides user notification of anomalous conditions by reporting events and issues via instant messaging.
